Hi Ecasounders,
Gverb docs (actually info from analyseplugin -- see below)
seems to say that this effect converts one input to two
outputs.
If I apply gverb naively to a one-channel input, I hear
one channel output.
ecasound -i one-channel.wav \
-el:gverb,80,9,0.9,0.75,0,-6,-8 \
-o alsa,stereo
If I use a chain setup as below with channel copy and
panning, I hear reverb on both channels with the signal
panned fully left, and no output with the signal panned
fully right. (Sample chainsetup below.)
This sounds suspiciously like the symptom I read about in
the user's manual:
5.5.3 Problems with panning mono files
Does that mean gverb outputs only a mono signal, and
therefore that I need to apply it to a mono section
of my chainsetup?
Is it possible to write a preset applying one effect
to each channel?
Is there some way to get the full two-channel goodness
of the gverb output under ecasound?
regards,
